. T on whom) it may concern.-

Be it known that I, CAssius U. BARLOW, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in Cookers, of which the following is a specification.

This invention relates to cookers, the object of the invention being to provide a cooking device in the form of an oven which is practically air-tight, and composed of material which will insulate the interior of the receptacle from the outside atmosphere and serve to maintain for a long period of time the temperature within the same.

It is well understood that after vegetables and other products are thoroughly heated and partially cooked upon an ordinary stove or in an oven the cooking operation will continue, provided such partially-cooked products can be retained in an air-tight chamber and the temperature thereof maintained at a high point for a long time; Food treated in this manner is more thoroughly cooked and is rendered more wholesome and palatable, and is in every way more desirable than food subjected to the ordinary rapid cooking operation.

To this end the invention consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.

In the drawings, Figure 1 is a perspective view of a cooker embodying the present invention.- Fig. 2 is a vertical sectional view of the same.

In the drawings I hav'ejshown a cooker of simple form, the same consisting. of a boxlike receptacle 1, rovided at one side with a door 2 hinged t ereto and provided with suitable fastenings means for retaining the:

door closed, any suitable method of rabbeting the door being employed to render the same air-tight.

Each of the walls of the receptacle or cooker, including the door thereof, embodies an outer thickness 3, which is composed of wood, a lining 4, of tarred paper, which is applied directly to the inner surface of the outer wall 3, a filling or additional thickness 5 of cork, and lastly an inside layer or thickness 6 of plaster, the said thicknesses being laid one upon the other in the order named, as shown in Fig. 2.

Under the preferred embodiment of this imvention the sides, top, and bottom of the receptacle are connected or fastened together 'at the corners by dovetailing, as shown at 7,

and at all other points, thus avoiding the use of nails or metallic fasteners, which are conductors of heat and cold.

A cooker constructed in the manner above described has been found by repeated tests to effectively insulate the interior of the cooker from the outside atmosphere and maintain the interior temperature at a high point,which will cause the cooking operation "to continue for a sufficient period of time to thoroughly CASSIUS U.
